On o" posits sides ci the rear end wall of thecham er are arranged two sockets which have metal screw sleeves G, H and heads or disks h of insulating material, respectively.

I gflhe disks are connected by a tie bolt i pass- 'butthefinner socket is insulated therefrom by an insulating washer 7c interposed between the same when a thermostat is used. When thevulcanizer is o erated without a thermo stat both inner an outer socket sleeves bea-r against the rear wall.- Upon screwing the lamp into the inner socket its terminals engage with the same and the tie bolt, respectively.

L represents the metal screw sleeve of a feed plug which connects with one of the feed wires and Z the central contact-oi the feed glug which connects with the other feed wire.

pon screwing this feed lug into the screw sleeve H of the outer socget of the rear wall the screw sleeve L thereof engages the metal vthreadof the outer socket and its central contact engages with the tie bolt, as shown in Fig. 4.

m represents the expansible and contractible coil or spring of the thermostat which is arranged within the chamber adjacent to the rear wall thereof and which is connected with' its ixed end to the metal screw sleeve of the inner orl lamp socket while its free end is adapted to movel toward and from an adjust ahle contact screw 7L arranged in the metal rear Wall of the chamber.

1When the temperature in the heating chamber is at o'r below normal the thermostatic coil is contracted and bears with its free end against the contact n, thereby closing the electric circuit through the lamp and causing the latter to develop heat but when the temperature of the heat in the chamber rises above normal the thermostatic'coil eX- @casse pandsand moves with its free end out of contact from the screw n, thereby breaking the 'electric circuit and extinguishing the lam -1ng the screw 'n forward or backward the de? grec of temperaturewhich it is desired to maintain in the heating chamber can be d'e'- termined. After adjustment the screw n is held in place by jam nuts o, a1 arranged on said screw and bearing against opposite sides of the rear Wall of the chamber.

ln order to enable the temperature of the heat within the chamber to be known a thermometer p is provided. This thermometer' may be passed through an o ening'formed in the chamber and engage with its bulb against the inner side of the chamber while its oppposite graduated end projects outside of the chamber to ermit of reading the same. ln Figs. i and 2 tlie heating chamber is provided with a-thermometer opening p1 in its ber, inner and outer sockets secured to OPPO- site sides ofsaid movable wall, the inner socket receiving said lamp and the outer socket adapted to receive the plug of feed wires, and a thermostatic switch for regulate ing the flow of electricity through the lain and comprising a thermostat-ic coil connecte at one end with the lam socket, and a screw 1 mounted on the remove. le head and adapted to be engaged b'y the other end of said coil,

suhstantially as Iset forth.
